War Of The Worlds (1953 SciFi Classic -color-)

http://www.imdb.com/title/tt0046534/



The Martians unchain a direct assault to our planet, with hundreds of invulnerable ships. The invasion takes place all over the world, and all the major cities are destroyed one after one; even the atomic bomb can't stop them. But, if the humans can't beat them, who can? Maybe something MUCH smaller than them...
